Abstract

An elevated or ground level vertical cylinder houses one or more propellers and/or turbines that are rotated by heated air convection within or around or above the cylinder. The rotating shafts of the propellers generate electricity in an area at the bottom of or below the cylinder. For added, improved air flow directions and volumes; and, for stabilization of the rotating shaft or shafts, a cone structure is disposed below the cylinder. Heat is directed to the cylinder by a plurality of sun tracking concave mirrors that are positioned in concentric circles at various heights. The cylinder may be composed of concrete, ceramics, metal compounds or other materials and operate with a surface temperature that may range from 70 to 1,300 degrees Fahrenheit. An optimized system may be constructed on less than one, one or more than one acre of land that could appear as a park like setting.

Description

First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 Invention Title Solar Energy Directed to a Cylinder Containing a Propeller Used to Generate Electricity [0001] Copyright and Trademark Notice [0002] This application includes material which is subject or may be subject to copyright and/or trademark protection. The copyright and trademark owner(s) has no objection to the facsimile reproduction by any of the patent disclosure, as it appears in the Patent and Trademark Office files or records, but otherwise reserves all copyright and trademark rights whatsoever. [0003] Background of the Invention [0004] (1) Field of the Invention [0005] The invention generally relates to the generation of electricity by use of a shaft rotated by air movement. More particularly, the invention relates to the use of an elevated cylinder receiving heat from concave solar tracking parabolic mirrors with the resulting upward air flow rotating a propeller and shaft. A circular pyramid base or cone structure is disposed upon the ground and within the cylinder to assist in air flow and securing the rotation shaft. [0006] (2) Description of the Known Related Art [0007] U.S. application 2013/0328319 A1 by Guo, published on December 12, 2013 is an example of the prior art’s penchant for using exterior shrouds or funnels to direct wind into a wind driven power generating device. The structure of Guo is incompatible with the disclosed embodiments. [0008] U.S. patent 8,232,665 issued to Sato on July 31, 2012 presents a columnar member comprising a plurality of wind inlets. The voids of the Sato system prevent effective heating of air near the turbine. Thus, Sato teaches away from the disclosed embodiments. [0009] U.S. patent 9,890,769 issued to Albert on February 13, 2018 presents a system used in building attic spaces where warmed air is pre-existing. Hot attic First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 air enters a funnel and is directed to a horizontally mounted turbine. The structure of Albert works with interior pre-heated air only and by design does not accept outdoor ambient air, which is intentionally kept out by virtue of the funnel and wall system. Moreover, the introduction of outdoor ambient air would cool the interior attic air and destroy the intended purpose of Albert. Thus, Albert teaches away from the disclosed embodiments which use outdoor air only. [0010] U.S. patent 9,543,945 issued to Coffey on September 27, 2016 discloses an exterior vertical wall system that comprises vertical spaced apart turbine blades. The space between the blades makes heating air near or within the system impractical. [0011] U.S. patent 9,291,150 issued to Bassett on March 22, 2016 discloses a cone support structure under or within a vertical cylindrical blade drum. The blade drum is in direct communication with ambient air. Bassett teaches away from the disclosed embodiments of using a cylinder to heat and enclose air used to turn a propeller or turbine. Moreover, the cone structure in Bassett does nothing to direct or improve the flow of air to the turbine blades. Bassett highlights a common shortfall in the art by requiring wind driven electrical generation to occur in windy areas. The use of wind power to generate is currently unduly limited to areas that are unusually windy. Thus, there is a need in the art for the presently disclosed embodiments. [0012] Brief Summary of the Invention [0013] The present invention overcomes shortfalls in the related art by presenting an unobvious and unique combination, configuration and use of elevated hollow cylinders, propellers using shaft in shaft rotational transmission, lower cone structures to direct air flow from the bottom of the cylinders and upwardly into the cylinders and to secure the rotation shafts. Outdoor ambient air within or near a hollow cylinder is heated with concentrated solar energy or concentrated solar power (CSP) by use of exterior parabolic concave reflectors or mirrors. The parabolic concave mirrors direct heat or CSP to the cylinder or First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 other exterior structure or heat retaining housing to cause the internal cylinder air to rise thus moving the propellers and rotating the shafts to generate electricity. [0014] An elevated cylinder may be made of concrete or other material of suitable thermal qualities and be capable of tolerating surface and internal temperatures in the range of 70 to 1,300 degrees Fahrenheit. The elevated cylinder is elevated to overcome shortfalls in the art that fail to draw air from the bottom of a system to provide a continuous air flow while at the same time heating the air near the propeller by heating the walls of the housing or cylinder. Alternative embodiments include cylinders or other exterior housing structures to be disposed at ground level, with ground level air inlets allowing ambient air to enter. The bottom edges of a cylinder may even be subterranean with duct work to allow air to enter the bottom portions of such a cylinder or housing. [0015] The disclosed embodiments overcome shortfalls in the related art by presenting an elevated and vertically oriented cylinder that is configured to heat air near a propeller or turbine while at the same time provide a continuous air flow to a propeller or turbine. [0016] The disclosed embodiments overcome shortfalls in the related art by the venturi effect created by the shape of the wind and shaft support cone which increases the air intake to the cylinder. Moreover, airflow is further increased by the convention heating that increases as temperatures increase upon the cylinder. [0017] The lower circular pyramid structure or cone structure provides an exterior concave arc for improved air flow into the bottom of the cylinder. The top end or top void of the pyramid structure provides an advantage of comprising a collar or bearing to further secure the vertically disposed rotating shaft. [0018] Alternative embodiments include the use of other shapes for the cylinder or outer structure or heat retaining housing. Such shapes include an hourglass, and funnel shapes with the wide base at the top or bottom. Various exterior structure shapes may provide a venturi effect drawing air upwardly at a greater rate of speed. First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 [0019] The cylinders or other heat retaining housings may be heated by a plurality of concave solar tracking parabolic mirrors. [0020] The known related art fails to disclose, suggest or teach the use of the disclosed physical structures or theory of operation.

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION [0072] The following detailed description is directed to certain specific embodiments of the invention. However, the invention can be embodied in a multitude of different ways as defined and covered by the claims and their equivalents. In this description, reference is made to the drawings wherein like parts are designated with like numerals throughout. [0073] Unless otherwise noted in this specification or in the claims, all of the terms used in the specification and the claims will have the meanings normally ascribed to these terms by workers in the art. [0074] Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise," "comprising" and the like are to be construed in an inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in a sense of "including, but not limited to." Words using the singular or plural number also include the plural or singular number, respectively. Additionally, the words "herein," "above," "below," and words of similar import, First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 when used in this application, shall refer to this application as a whole and not to any particular portions of this application. [0075] Referring to FIG.1, a solar heated elevated cylinder system 100 is shown in a park-like setting. A wind and shaft support cone 200 has a bottom portion defining a bottom void that has a greater diameter as compared to the upper portion that defines the upper void. The proportionally or shape overcomes shortfalls in the related art by providing a stable base while providing room for air flow at the bottom of the cylinder. [0076] At the top portion of the cylinder 110, and inside surface 114 defines a wind blade void 120. A distal tip 305 of a propeller or upper propeller may be contained with the wind blade void to provide added stability to the propeller. [0077] Referring to FIG.2, a cylinder is shown having an outer surface 112 with the outer surface receiving solar energy or heat from a plurality of mirrors 600 that are sometimes supported by support poles 630. A support structure 150 positions the bottom portion 117 of the cylinder above the ground. This above ground positioning in conjunction with the wind and shaft support cone provide operational advantages in that ambient air may be drawn from the bottom of the cylinder and further allowed or directed into the cylinder by the narrow or narrowing portions of the wind and shaft support cone 200. [0078] Disclosed embodiments may include one or more turbines, propeller systems or other power generation systems disposed at or near or in proximity to the cylinder so as to take advantage of concentrated solar energy or concentrated solar power (CSP) produced by the exterior parabolic concave reflectors or mirrors. [0079] Referring to FIG.3, a dislocated system 100 is shown in conjunction with electric vehicles and electric vehicle charging stations. The relative compact design of the system allows for a plurality of systems to be installed along roadways or freeways. First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 [0080] Referring to FIG.4, a disclosed system 100 is shown in the center of a plurality of concave parabolic reflective mirrors disposed upon support poles. Such mirrors may be movable and programed to rotate to track the position of the sun or otherwise be solar tracking. The mirrors may be positioned in concentric circles around the cylinder and elevated at varying heights to maximize the solar energy or heat directed to and delivered to the cylinder. [0081] Referring to FIG.5A a sectional view of a disclosed embodiment shows the inside surface 114 of the cylinder defining a wind blade void 120. Optionally a track may be used to secure or guide the tip of a blade during movement with the track attached to the inside surface of the cylinder. [0082] The upper void 210 of the wind and shaft support cone will accept a rotating shaft. The upper void may also contain a bearing or other mechanism of securing the rotating shaft or concentric shafts in a two propeller / turbine system. [0083] Below ground level 700 or within the cone, a power generator 400 may be in mechanical connection with the rotating shaft to convert the rotation of the shaft into electricity. [0084] With respect to the inner and/or outer surfaces of the cylinder and/or cone structure, upwardly spiraling protrusions channels, bumps, rivulets, bands, rifling or cyclonic twisting may be of benefit in increasing upward airflow convection speed. Such upward spiraling caused by such spiral grooves overcomes shortfalls in the art by maximizing the probability to intermix for mingled-molecular heat conduction/absorption/transfer off of the cylinder and conde surfaces. Expanded per air molecule separation-distances therefore occurs to lighten the air; which increases upward airflow convection speed. The inner cylinder lightened air mass [i.e., greatly lowered air pressure inside cylinder] will then be constantly energized via heat derived from exterior Concentrated Solar Power “CSP” mirrors. [0085] Referring to FIG.5B, a power generator 400 is shown in connection with the rotating shaft. First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty. Steven A. Nielsen, Reg. No. 54,699 Customer No. 45004 [0086] Referring to FIG.6, a sectional view of a disclosed system 100 is shown with the lower edge 218 of the wind and shaft support cone resting on the ground 700. Reflective mirrors are directing sunlight towards the cylinder. A top or upper propeller 300 is shown disposed at the upper end of the cylinder. [0087] Referring to FIG.7, a duel propeller or dual turbine system is shown with an upper propeller 300 in mechanical connection with a rotational shaft 320, with said rotational shaft disposed within a hollow second rotational shaft of the lower propeller 350. FIG.7 also shows an upper propeller mounted above the top edge of the cylinder. Such a configuration allows the lower propeller 350 the maximum amount of air flow. The excess air flow rising past the lower propeller may then be utilized by the upper propeller, with the upper propeller disposed an at upper distance so as to not slow down the airflow used by the lower propeller. The upper propeller may be supported by a frame structure and contained in a circular track. The two shafts may separately integrate or be in attachment to the power generator. [0088] FIG.8 is a sectional view of a disclosed CO2 removal system 500 using a chimney system and other components integrated with the disclosed elevated cylinder system 100. The artful use of filters combined with the significant air flow achieved by the cylinder system enables the extraction of CO2 on an unprecedented scale as CO2 collectors strip CO2 out of the wind stream of the system. [0089] In general, air is dawn though the fabric 545 covering the perimeter platform skeleton and air is drawn in through the fabric 520 around the frame of the chimney funnel 510. [0090] FIG.9 depicts a plurality of disclosed CO2 removal systems 500 connected by roads. [0091] FIG.10 depicts one disclosed CO2 removal system that includes a plurality of CO2 and water storage containers 560. First Named Inventor: Warren Arthur Burtis; Docket: BurtisPCT Pat. Atty.
